Abstract
A display device includes a display panel, a main vibrator disposed on the display panel configured to generate a main vibration wave, and a plurality of sub-vibrators disposed on the display panel and spaced apart from the main vibrator and configured to the plurality of sub-vibrators configured to generate sub-vibration waves, respectively, wherein the plurality of sub-vibrators includes a first sub-vibrator disposed at a first distance from the main vibrator in a plan view, the first sub-vibrator being configured to generate a first sub-vibration wave; and a second sub-vibrator disposed at a second distance from the main vibrator in the plan view, the second sub-vibrator being configured to generate a second sub-vibration wave having a phase different from the first sub-vibration wave, and, wherein the second distance is different from the first distance.
